LTE spectrum: How much do the big carriers have?

摘要

The top u.s. carriers over the past year have stepped up their efforts to grab more spectrum for 4G wireless data services needed to accommodate an exploding and seemingly insatiable population of iPhone, iPad and other mobile device users. To get a sense of just how much addi- tional bandwidth carriers will need, consider that Ericsson's most recent Traffic and Market Data report predicted that global mobile data traffic will grow tenfold between now and 2016. What's more, the FCC has projected the nation's wireless carriers will face a 275MHz "spectrum deficit" by 2014 if no new spectrum is opened up for use.
